0.2^5*0.4^5*12.5^6计算或化简,5
0.2^5*0.4^5*12.5^6计算或化简,5

0.2^5*0.4^5*12.5^6计算或化简,5
0.2^5*0.4^5*12.5^6
=(0.2×0.4×12.5)^5×12.5
=1^5×12.5=1×12.5=12.5

0.2^5*0.4^5*12.5^6
=(2/10)^5*(4/10)^5*(125/10)6
=2^5*4^5*125^6/10^5*10^5*10^6
=2^5*2^10*5^18/10^16
=2^15*5^18/10^16
=(2*5)15*5^3/10^16
=10^15*5^3/10^16
=5^3/10
=125/10
=12.5
